PolygonPrismMeshUtils::HalfEdge Struct Reference

#include <PolygonPrismMeshUtils.h>

Public Attributes
Face *	m_face = nullptr
	The face this half-edge belongs to.
AZ::Vector2	m_origin = AZ::Vector2::CreateZero()
	The point where this half-edge meets the previous half-edge.
HalfEdge *	m_prev = nullptr
	The previous half-edge.
HalfEdge *	m_next = nullptr
	The next half-edge.
HalfEdge *	m_twin = nullptr
	The half-edge which shares this edge, or nullptr if this edge has no adjacent face.
float	m_prevAngle = 0.0f
	The internal angle between this half-edge and the previous half-edge.
float	m_nextAngle = 0.0f
	The internal angle between this half-edge and the next half-edge.
bool	m_visited = false
	Marks if the half edge has been visited during the process of matching up twin edges.
bool	m_dirty = false
	Marks if an update is required because an adjacent internal edge has been removed.

Detailed Description

A half-edge in a doubly connected edge list (a data structure for efficiently manipulating meshes). An edge connecting two adjoining faces in the mesh is represented as two oppositely directed half-edges, which each half-edge belonging to one of the faces, and owning a pointer to its twin in the other face.
